Description

Technical Field

[0001] This utility model relates to the field of fuel cell processing technology, and more specifically, to an ultrasonic microporous structure fuel cell proton exchange membrane processing equipment. Background Technology

[0002] As a core component of fuel cells, the proton exchange membrane (PEM) directly determines the ion conduction efficiency, sealing performance, and overall lifespan of the fuel cell through its structural integrity, surface coating uniformity, and microporous characteristics. Among these, ultrasonic microporous PEMs, utilizing a uniform micropore array constructed with ultrasonic processing technology, can significantly improve the proton conduction rate and gas barrier performance of the membrane, making them a key material in the field of high-performance fuel cells. In the industrial processing of ultrasonic microporous PEMs, the coating process is a crucial link between micropore fabrication and membrane electrode assembly. It is essential to achieve uniform coating thickness and no coating buildup at the edges while ensuring the microporous structure remains intact. This prevents sealing failures and gas leakage during subsequent assembly, while also ensuring that the mass transfer channels of the micropores are not blocked by the coating.

[0003] Currently, most ultrasonic microporous proton exchange membrane coating equipment is based on improvements to traditional membrane processing equipment. During the coating process, the adhesive is affected by surface tension and coating pressure, and tends to accumulate in the edge area of ​​the ultrasonic microporous proton exchange membrane, forming adhesive buildup. Since the micropores at the edge of this type of membrane are directly exposed, adhesive buildup not only leads to abnormal membrane edge thickness, affecting subsequent assembly and sealing, but may also cause local mass transfer channel blockage due to adhesive diffusion into the edge micropores, weakening the performance advantages of the microporous structure. Existing equipment mostly relies on manual scraping or fixed scraper scraping: manual scraping is inefficient and inaccurate, and easily scratches the fragile microporous membrane edges; fixed scrapers cannot be adapted to ultrasonic microporous proton exchange membranes of different widths, resulting in the inability to effectively remove adhesive buildup at the edges of some membrane sizes. At the same time, most of the scraped adhesive is directly discarded without recycling, resulting in a large waste of adhesive resources and increased production costs. Utility Model Content

The glue inlet of the glue pump is fixedly connected to the conveying pipe.

[0009] As a preferred embodiment of this utility model, the top of the processing box is provided with symmetrically distributed through grooves, the width of which is greater than the outer diameter of the conveying pipe.

[0010] As a preferred technical solution of this utility model, a glue injection box is provided above the fixed roller, a glue coating roller is rotatably connected to the bottom inner wall of the glue injection box, and symmetrically distributed vertical guide rods are fixedly connected to the top of the glue injection box. The vertical guide rods are slidably connected to the processing box, and a cylinder is provided between the two vertical guide rods. The cylinder is fixedly connected to the top outer wall of the processing box, and the driving end of the cylinder is fixedly connected to the glue injection box.

[0011] As a preferred embodiment of this utility model, a first guide roller is symmetrically distributed below the side of the fixed roller away from the second guide roller.

Then, the vertical rod and the collection box are moved through the connecting rod. The position of the scraper is adjusted according to the different widths of the proton exchange membrane, so that the scraper is attached to the edge of the proton exchange membrane. When the proton exchange membrane moves between the two scrapers after being coated with glue by the glue roller, the scraper scrapes off the glue accumulated at the edge of the proton exchange membrane. The glue is guided by the scraper and falls into the collection box under the action of gravity for collection. The glue pump returns the glue collected in the collection box to the recycling tank through the delivery pipe, which facilitates glue scraping and avoids glue accumulation at the edge of the proton exchange membrane, which affects the processing effect.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 5 As shown, this utility model provides an ultrasonic microporous structure fuel cell proton exchange membrane processing equipment, including a processing box 1. A fixed roller 11 is rotatably connected to the inner wall of the processing box 1. A second guide roller 14 is symmetrically distributed on one side of the fixed roller 11 and is rotatably connected to the inner wall of the processing box 1. A collection box 15 is symmetrically distributed on the side of the fixed roller 11 near the second guide roller 14. A scraper 16 is provided in the upper part of the collection box 15. An arc-shaped rod 17 is fixedly connected to the side of the scraper 16 away from the fixed roller 11 and is fixedly connected to the collection box 15. A support plate 22 is fixedly connected to the top inner wall of the processing box 1. A mounting base 21 is fixedly connected to the bottom of the support plate 22. Horizontal guide rods 19 are slidably connected to the inner walls of both ends of the mounting base 21. A horizontal guide rod 19 extends out of the mounting base 21 and is fixedly connected to a vertical rod 18, which is also fixedly connected to the collection box 15. Below the horizontal guide rod 19, there is a connecting rod 20 fixedly connected to the vertical rod 18. Movable blocks 23 are fixedly connected to the outer walls of the two connecting rods 20 that are close to each other. A bidirectional screw 24 is rotatably connected to the bottom of the mounting base 21, and the outer wall of the bidirectional screw 24 is threadedly connected to the movable block 23. The bidirectional screw 24 rotates to drive the movable block 23 to move, so that the two connecting rods 20 move closer to each other, thereby causing the vertical rod 18, the collection box 15, and the scraper 16 to move. The scraper 16 moves to abut against the edge of the proton exchange membrane, so that when the proton exchange membrane moves, the scraper 16 scrapes off the glue at its edge, which is then collected by the collection box 15.

[0017] The mounting base 21 has a groove 26 at its bottom, the bidirectional screw 24 is located in the groove 26, and the inner wall of the groove 26 is slidably connected to the movable block 23, so that the movement of the movable block 23 is guided by the groove 26.

[0018] Among them, a motor 25 is fixedly connected to one side of the outer wall of the mounting base 21. The output shaft of the motor 25 is fixedly connected to the bidirectional screw 24. The motor 25 drives the bidirectional screw 24 to rotate, causing the movable block 23 to move, so that the two movable blocks 23 can move closer to each other or further away from each other.

[0019] The bottom of each of the two collection boxes 15, which are far apart from each other, is fixedly connected to a conveying pipe 7. The top outer wall of the processing box 1 is fixedly connected to a recycling box 5. The two sides of the recycling box 5 are fixedly connected to symmetrically distributed glue pumps 6. The glue inlet of the glue pump 6 is fixedly connected to the conveying pipe 7. The glue collected in the collection box 15 is conveyed through the conveying pipe 7 by the glue pump 6 and then concentrated in the recycling box 5 for collection.

[0020] The processing box 1 has symmetrically distributed through grooves 8 on its top. The width of the through grooves 8 is greater than the outer diameter of the conveying pipe 7. The through grooves 8 prevent obstruction when the conveying pipe 7 moves.

[0021] The fixed roller 11 is equipped with a glue injection box 10 above it. The bottom inner wall of the glue injection box 10 is rotatably connected to a coating roller 12. The top of the glue injection box 10 is fixedly connected to symmetrically distributed vertical guide rods 4. The vertical guide rods 4 are slidably connected to the processing box 1. A cylinder 3 is provided between the two vertical guide rods 4. The cylinder 3 is fixedly connected to the top outer wall of the processing box 1, and the driving end of the cylinder 3 is fixedly connected to the glue injection box 10. The glue injection box 10 is moved by the cylinder 3, thereby adjusting the position of the coating roller 12, so that when the proton exchange membrane is between the fixed roller 11 and the coating roller 12, the coating roller 12 coats the proton exchange membrane with glue.

[0022] The fixed roller 11 is provided with a symmetrically distributed first guide roller 9 below the side away from the second guide roller 14. The first guide roller 9 is rotatably connected to the processing box 1. The processing box 1 has symmetrically distributed material inlets 2 on one side, and the material inlets 2 are located on the side of the first guide roller 9 away from the second guide roller 14. The processing box 1 is equipped with a fan 13 on the other side, and the fan 13 is located on the side of the second guide roller 14 away from the first guide roller 9.

[0023] Working principle and usage process of this utility model: In this application, during use, the proton exchange membrane enters the processing box 1 through the upper feed port 2, then passes through the bottom of the first guide roller 9 and the top of the fixed roller 11, and is then guided by the second guide roller 14 and the bottom of the lower first guide roller 9 to the lower feed port 2 for discharge. The driving end of the cylinder 3 drives the glue injection box 10 to move, thereby adjusting the position of the glue coating roller 12 so that the glue coating roller 12 contacts the proton exchange membrane to apply glue to the proton exchange membrane. After the glue coating is completed, the fan 13 is started and blows a directional airflow to the proton exchange membrane in the conveying process. By accelerating the curing of the glue layer, optimizing the uniformity of the glue layer, and stabilizing the membrane conveying state, it provides a guarantee for subsequent glue scraping and processing accuracy. In this application, during the glue scraping process, the motor 25 is started, and the output shaft of the motor 25 rotates, driving the bidirectional screw 24 to rotate, which in turn causes the two movable blocks 23 to move closer to each other. This, in turn, drives the vertical rod 18 and the collection box 15 to move through the connecting rod 20. The position of the scraper 16 is adjusted according to the different widths of the proton exchange membrane, so that the scraper 16 is attached to the edge of the proton exchange membrane. When the proton exchange membrane moves between the two scrapers 16 after being coated with glue by the glue roller 12, the scraper 16 scrapes off the accumulated glue at the edge of the proton exchange membrane. The glue is guided by the scraper 16 and falls into the collection box 15 under the action of gravity for collection. The glue pump 6 recycles the glue collected in the collection box 15 into the recycling tank 5 through the delivery pipe 7, which facilitates glue scraping and avoids glue accumulation at the edge of the proton exchange membrane, which would affect the processing effect.
